CPU
BOARD
The CPU board is based on the Digicolor2 circuit which performs in particular the function of micro-
processor.
The executable code is stored in the flash memory Z460.
This flash memory is divided in two zones: a zone reserved for the storage of the code and a zone
reserved for the storage of the documents.
The code is loaded from this flash memory into SDRAM, and the microprocessor executes its instruc-
tions from the SDRAM.
Before printing, the documents to be printed are stored as bitmaps in SDRAM.
The SDRAM is also used as the working memory for the Digicolor2.
